“…[40][41] The electrode was operated using pure oxygen in the ORR mode and no electrode deterioration was observed in 120 cycles. Similar highly-active lead-iridium pyrochlore oxides were also reported by ten Kortenaar et al 42 Bismuth ruthenate is among the most stable pyrochlore oxide material that has been reported. 43 Yeager et al have used ionically conducting polymers and anion exchange membrane layers to improve the stability of air electrodes using pyrochlore catalysts.…”

This article discusses a technology inherent in rechargeable metal-air batteries and reversible fuel cells, namely a bi-functional oxygen electrode. The criteria of a good bi-functional oxygen electrode are presented, and the various sources of overpotential at such an electrode are discussed. The various materials used in bi-functional oxygen electrodes are described, both for secondary metal-air batteries and for regenerative fuel cells. The intricacies of the structure of the bi-functional electrode are elucidated, including the requirement of two separate zones for oxygen reduction and oxygen evolution reactions. The challenges associated with such electrodes (e.g., carbonation) and the future directions of research required to advance the technology of bi-functional electrodes are described.

“…Pyrochloretype oxides have the general formula A 2 [B 2Àx A x ]O 7Ày , where A ¼ Pb or Bi, B ¼ Ru or Ir, 0 < x < 1 and 0 < y < 0.5. Horowitz and coworkers [83] [84]. The pyrochlores give a low Tafel slope, 24e40 mV dec À1 and their high activity of these oxides was explained in terms of their oxygen deficiency.…”
